Matthias Krüger 40c97a9279 Rollup merge of #149501 - lcnr:no-hard-error-on-norm-failure, r=lqd,oli-obk ... CTFE: avoid emitting a hard error on generic normalization failures Fixes rust-lang/rust#149081. The fix is quite unsatisfying and should not be necessary, cc rust-lang/rust#149283. That change is significantly more involved. This temporary fix introduces some unnecessary complexity and may hide other type system bugs. cc ````@rust-lang/types```` I think we should try to fix issue rust-lang/rust#149283 in the near future and then remove this hack again. I originally intended a more targeted fix. I wanted to skip evaluating constants in MIR opts if their body was polymorphic and the current generic arguments still reference generic parameters. Notes from looking into this: - we only fetch the MIR in the `eval_to_allocation_raw` query - figuring out which MIR to use is hard - dealing with trivial consts is annoying - need to resolve instances for associated consts - implementing this by hand is hard - inlining handles this issue by bailing on literally all normalization failures, even the ones that imply an unsoundness - `try_normalize_after_erasing_regions` generally does two things - deal with ambiguity after inlining - deal with error tainting issues (please don't, we should stop doing that) - CTFE could be changed to always silently ignore normalization failures if we're in a generic body - hides actual bugs <- went with this option r? types		2025-12-04 08:46:20 +01:00
